GLASS-SIGN-LE'ITER FASTENING.

i Application filed March 4,1926, Serial m. 92,322.

My invention relates generally to glass signtletters', numerals, andthelike, and more particularly to means for'fastening said 1et= ters tov abase or background, the principalL objectsofmy invention beingto providerelatively simple" and praotiealmeans for fastening glass or porcelainsign letters to a base and which fastening means is especially designedto eliminate breakage of the sign 1 letters while the same are beingsecured to a base or panel.

It will be understood that letters and figures of glass, porcelain, andlike brittle material are largely usedin the formation of signs and forhouse numbers, and when these letters, numerals and the like, aresecured to a base or panel that forms the background for the sign, theseating of the fastening devices, which are usually screws or nails,

very frequently results in breakage of the frangible material from whichthe letters and characters are composed.

It is the purpose of'my invention to provide si n letters of glass,porcelain, and the like, with notches that are adapted to receive thefastening screws, and which notches are constructed so that when theheads of the screws enter said notches they will engage beveled orinclined faces that tend to move the screws away from the bodies of thesign letters, thereby preventing said screws or the heads thereof fromexerting stresses on the letters that would tend to break or fracturethe same.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of parts thatwill hereinafter be more fully described and claimed and illustrated inthe 4 accompanying drawing, in which Fig. 1 is an elevational view of asign letter that is constructed in accordance with the principles of myinvention.

Fig. 2 is an enlarged elevational view of a portion of a sign letterthat is notched in accordance with my invention for the recep tion ofthe fastening device.

Fig. 3 is an enlarged cross section taken on the line 3-3 of Fig. 1. v

Fig. 4 is a detail section of a modified form of the sign letterfastening device.

Referring by numerals'to the accompanying drawing, 10 designates thebody of a letter, numeral, or like character, that is formed of glass,porcelain, or the like, and

arranged at suitable points on the edges of the'body of'isaid letter orcharacterare short outwardly-projecting lugs 11;

Formed the outer'portionbf eacli lug 1s an arcuate or: substantiallysemi-"circular" notch '12"; and: the faceof saidinotch is in} clined orbeveled as designated by 13.

Glass sign letters are usually applied to a panel or base by means ofscrews such as 14 I and when these screws are used in connection withthe letter having the notched lugs 11, said screws are positioned inthenotches 12 and as they are driven downwardly into the base or panel,the lower edges of the heads of the screws will bear against theinclined or beveled surfaces 13 of the notches and as a result of thisengagement, as said screws thereby eliminating the pressure and stressesthat would otherwise tend to fracture and break the lugs or the portionsof the bodies of the letters with which the screws engage. As a resultof the use of my improved fastening means, the breakage of glass signletters and the like is minimized, thus producing a decided economicadvantage.

Wh1le I have shown and described the screw-receiving notches as beingformed in lugs that project from the edges of the bodies of the signletters, it will be understood that these arcuate bevel-faced notchesmay be formed directly in the edges of the letters or characters withthe same advantageous results.

Thus it will be seen that I have provided simple and eificient means forsign letter of glass, porcelain and the like, and which fastening meansmay be employedswithout dethe circular base portions of push buttons,

electric bells, and the like, or in fact any glass or porcelain memberthat is attached by means of screws to a base of wood or the like.

It will be understood that minor changes in the size, form andconstruction of the various parts of my iinprovcd glass sign letterfastening may be made and substituted for those herein shown anddescribed without departing from the spirit of my invention, the scopeof which is set forth in the appended claims.

I claim as my invention:

1. As a new article of manufacture, a sign letter composed of vitrifiedmaterial, an in tegral lug projecting outwardly from the edge of thebody of the sign 1e ter, which lug is provided in its edge with anarcuate screw receiving notch, the entire face of which is beveledwhereby the head of 9.

screw that is seated in said notch will be forced away from the lug as aresult of contact with said beveled face.

2. As a new article of manufacture, a sign letter formed of vitrifiedmaterial, a lip projecting from the edge of the body of said letter, theedge of said lip being provided with an arcuate screw receiving notchand the entire inner face of which notch is Leveled whereby the head ofa screw that is seated in said notch will be forced away from the lug asa result of contact with said beveled face.

In testimony whereof I afiix my signature.

ALBERT HAMILTON FoRGER.
